To model beams and bracings for industrial steel structures using TSD

AIM :   

• To define steel beam and model for intermediate level.
• To define rafter beam and model as roof,also to add frame action at grids in one direction.
• to locate bracingas per design intent.

INTRODUCTION :   

A rafter is a structural component that is used as part of a roof construction and is one of a series of sloped structural members that extend from the ridge or hip to the wall plate, downslope perimeter, and that are designed to support the roof deck and its associated loads.

A bracing system is a secondary but essential part of a structure. A bracing system serves to stabilize the main girders during construction, to contribute to the distribution of load effects and to provide restraint to compression flanges or chords where they would otherwise be free to buckle laterally.

A steel moment-frame is an assembly of beams and columns, rigidly joined together to resist both vertical and lateral forces.

PROCEDURE :   

• Open the Tekla structure software 
• And then open the week2 challenge file.
• Now go to levels and select Ground floor
• Now go to manage property and create the new beam 
• And then model the beam.

• Now Model the secondary beams in the intermediate floor as per the plan.

• Now model the beams in the roof level.

• Now create the frames at every grid.

• Now create the rafter.

• And then model the rafter.

• Now create the ridge rafter to support the rafter.

• Now create the steel brace 

• Now model the wall panels.

• Now model the roof panel.

• Go to slab property and create the slab.
• And model the slab.

Result :   

• Primary and secondry beams are modeled in intermediate level (first floor).
• Rafter beam is defined and modeled as roof.
• Bracing is done as per requirement.
• Moment frame action in one direction is modeled.
